ESO eso1333: Snow in an Infant Planetary System — A frosty landmark for planet and comet formation. A snow line has been imaged in a far-off infant planetary system for the very first time.

A snow line has been imaged in a far-off infant planetary system for the very first time. The snow line, located in the disc around the Sun-like star TW Hydrae, promises to tell us more about the formation of planets and comets, the factors that decide their composition, and the history of the Solar System. The results are published today in Science Express.
